[PATCH] drivers/staging/rtl8188eu remove 5GHZ specific code

My first patch.
This based from linux-next tree.
Removes code valid only for 5 HGz, as per the TODO, and also some formating issues.
If this device is only supported for sub 5GHZ hardware than this
change should not harm its intended audience. The caller 
of Hal_GetChnlGroup88E() does not check for false.
